IPC: G01N3/40
Filed: 1923-05-12
Abstract: 216,680. Benton Scale Co., Ltd., and Benton, W. A. May 12, 1923. Testing hardness of materials.-The specimen is arranged to take the greater part of the weight and to provide a pivotal support for a suspended pendulous mass adapted to oscillate under torsional moments set up in its suspension, an observation of the angle of decrement of the oscillations of the mass or of the period of time taken to reach a given decrement affording a measure of the hardness. The frame of the apparatus comprises a vertical member 4, a base member 5, and a bridging member 7 disposed in a plane at right angles to the plane of the member 4. The pendulous mass 9 provided with a hardened point 10 is suspended by an elastic wire or strip 14 from the lower end of a slotted link 13 guided in the bridge piece 4f, the link being suspended by a spring 12 from a screwed stem 11 adjustably mounted in the upper end of the frame member 4. Passing through the link 13 is a pivoted lever 18, - the free end of which bears a hardened strip engaged by the point of a screw 20 operated by a hand wheel. Mounted on the lower end of the bush 29 in the cross piece 4e is an annular collar 30, from which project diametrically two aligned arms 30<a>, one of which is provided with a. handle 32, while each arm at points equidistant from the axis of the machine carries projections 33 with adjustable contact screws 33<a>. These are adapted to engage simultaneously two stops 28 on. a diametrically arranged strip 27 attached to the mass 9. The mass 9 is provided with a graduated drum 25, which moves relatively to a fixed index 26, and with two adjustable masses 23 to vary its moment of inertia. The lower section. of the mass 9 is provided with a hole 34 axially aligned with the axis of rotation of the mass. A needle carried by a slotted pin 35 carried in turn upon a pivoted lever 36 is adapted to engage the hole 34 to centralize the mass. In use, the specimen is placed on the table 8, and the latter and the lever 18 adjusted so that the point 10 does not quite contact with the specimen while the spring 12 is given a predetermined slight tension. The handle 32 is moved and the mass 9 moved through a predetermined angle defined by a stop, not shown, on the member 4. The lever 18 is then towered until quite free from the end of the slot in the link 13 and the weight of the mass is taken by the specimen with the exception of the small predetermined amount taken by the spring 12 which may be adjusted by the nut 15 to secure an exact amount. The finger 38 is now pressed down against the spring 41 and the needle lowered out of the hole 34 in the mass, the handle 32 being moved back to its original position allowing the mass to oscillate. A stop-watch may be embodied in the apparatus adapted to start on the commencement of the oscillation of the mass 9.

Title: Improvements in or relating to catalysts for the treatment and conversion of hydrocarbons
IPC: C10G35/06
Filed: 1954-05-04
Abstract: A catalyst for the treatment and conversion of hydrocarbons comprises molybdena supported on activated alumina and promoted by the addition of a zinc halide in an amount from 1-20 per cent by weight of the total catalyst.  Zinc chloride and fluoride are specifically mentioned and the catalyst may also contain zinc oxide or aluminium chloride.  The molybdena content of the catalyst may be from 5-20 per cent by weight.  The alumina-molybdena catalyst may be prepared (a) by wet impregnation of alumina with ammonium molybdate, molybdic acid, or molybdenum blue (b) by dry mixing alumina with molybdic acid or ammonium molybdate or (c) by coprecipitation from solution or mixed hydrosols.  High density particles of precipitated alumina may be prepared by adding gluconic acid before precipitation.  A heat-stable alumina base is prepared from a peptized alumina gel by the addition of 0.5-5 per cent by weight of silica.  In an example, a solution of aluminium sulphate containing sulphuric acid is mixed with a solution containing sodium aluminate, sodium silicate, gluconic acid and sodium hydroxide; the precipitate is washed, peptized with glacial acetic acid, wet impregnated with a solution of zinc chloride, dried, calcined, and impregnated with an ammoniacal solution of ammonium molybdate.  After drying and calcining, the catalyst is used for hydroforming naphtha and is found to give higher yields of gasoline than a catalyst not containing zinc chloride.

Patent GB-131587-A (GB)
IPC: F02B75/02
Abstract: 131,587. Duvauchelle, G. A. Aug. 19, 1918, [Convention date]. Cylinders receiving liquid fuel.-In an engine using high compression and a heavy fuel, the methods of working by igniting at constant volume and constant pressure are combined. The fuel is injected into the interior of a perforated valve during a compression or suction strode, the more volatile portion of the fuel mixing with air in the cylinder and being ignited by the heat of compression, the resulting explosion igniting the remainder of the fuel which burns at constant pressure. Air for scavenging and the formation of the charge may be compressed in the crank chamber or in a separate pump. Fuel is drawn by an air pump having terminal admission ports through a passage 14 and past a governor and hand-controlled needle valve 12 into an annular space 10 surrounding the stem of a valve 1 into the interior of which the fuel is ultimately forced through orifices 3 when the valve is opened. The fuel is forced into the valve by compressed air from the pump, the volatile portion of the fuel escaping into the interior of the cylinder through the ports 4 whilst the heavier portion remains in the portion 5 of the valve until the cylinder temperature and pressure are raised sufficiently to expel it. The admission ports to the air pump are controlled by an adjustable ring valve, the degree of compression in the pump determining the time of ignition of the volatile portion of the fuel.

Title: Improved apparatus for the mercerisation of cellulose fibres of all kinds
IPC: D06B7/02
Filed: 1934-06-07
Abstract: Cellulose fibres in loose form, for example, as sliver or roving, or as finished yarns, or in fabrics or articles, are conveyed between two conveyer bands of fine mesh sieve material which are continuously and firmly pressed together, throughout the mercerization and subsequent washing treatment, between two sieve chains.  In a modification, a perforated drum may take the place of one of the sieve chains, tension in the other chain pressing the conveyer bands against the drum, or alternatively, and as in the case where two sieve chains are employed, the chain and drum (or the sieve chains) may be pressed together by clamps, which are automatically engaged upon contact of the sieve chains with the conveyer bands and are automatically disengaged shortly before the fibre is discharged from between the conveyer bands.  The clamps may be pressed together by springs or by weights.  Fig. 1 shows an arrangement wherein two endless conveyer bands b of permeable very fine meshed metal sieve material convey material introduced there-between between two endless sieve belts or chains c which are pressed firmly together by means of clamps engaging their opposite sides.  The material thus held is subjected to jets d of mercerizing and washing liquid, opposite to <PICT:0440867/IV/1> <PICT:0440867/IV/2> which are suction boxes e. An arrangement wherein one of the sieve belts or chains c is replaced by one or more drums h is shown in Fig. 6.  In this case, the pressure required is applied by tension in the remaining chain c or by means of clamps, as before.

Abstract: 1,104,238. Automatic control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. March 28, 1966 [March 30, 1965], No.13564/66. Heading G3R. In a system for automatically controlling a variable in response to an error voltage corresponding to deviation of the variable, a capacitor is connected periodically to the error voltage and to a high gain control amplifier having capacitive feedback. As described, a variable to be controlled is measured by an instrument which operates a potentiometer forming, with a setpoint potentiometer, a bridge circuit the output of which is periodically applied to an auxiliary capacitor. The voltage across the latter is periodically applied to the input of a high gain amplifier, having capacitive feedback, the output of which controls the variable. The output of the bridge circuit may be applied to the auxiliary capacitor directly or in series with the feedback capacitor. In the latter case a variable resistance may be included in the circuit to give desired proportions of proportional and integral control. In a system in which a digital computer normally controls a plurality of variables through high gain capacitive feedback amplifiers, a rotary selector switch may substitute control through auxiliary condensers associated with each variable in turn if the computer fails.
